Hi Henk,

no problems with O/OEROS decoding from our morning passes. You can see a lot
of decoded packets on our SatBlog http://www.dk3wn.info/p/?p=18463

The satellite was minus 2 KHz from the calculated frequency by TLE on the
mission dashboard website. I used SatPC32 for comparison only but tuned

I could grab only a few packets on the afternoon passes. 

73, Mike

Betreff: [amsat-bb] New sat's experiences ?

Just to cheer up others with poor results - you're not alone :-)

FASTRAC downlink at 145.825:   ISS + other QRM and clearly my 9k6 is not
Quite a few packets heard, nothing decoded. Here I (my station) clearly

FASTRAC & O/OREOS downlink at 437: lot of QRM (50Hz humm, 50 KHz wide at

O/OREOS: Yes I did hear it, 4 second packet period interfal, but I could not
Others (eg DK3WN) have better results. Seems 4 KHz above official freq, all
the time,
so I assume its not due to the keplerset (else that would not be 4 khz all
the time ?)
Your experiences ?
Mike: what does your SDR analysis say wrt the frequency ?

O/OREOS keplerset: accepted by HRD (go to keplers, click add file (next to
the list of
URLs and upload the keplerset manually. But: I suspect it to be invalid,
some programs
do not accept the O/OREOS keplerset, HRD only accepted after I turned off
the checksum check.

Anyway lot of new signals to hunt for.
(and 145.825 will become VERY busy)

Looking forward to hear you results !
